Application filed. May 25,

T 0 all whom it may concern:

Be it known that I, MARonL AoHAR'r, a citizen of the Republic of France,residing at 21 Rue. Victor Masse, city of Paris, France, have inventedcertain new and useful Improvements in Supporting Devices for the Heelsof Footwear; and I do hereby declare that the following is afull,.clear, and exact description of the invention, sun-h as willenable others skilled in the art to which it appertains to make and usethe same.

The heels used for boots and specially ladies, shoes are rarely fastenedsecurely to the sole for resisting for a long time the oblique forcecaused by walking. Thus, after a short usage, the nails or pins whichfasten the heel to the sole, instead ofremaining perpendicular to thesole, become inclined bit by bit and the heel gradually gives way underthe weight of the body, often causing the fall of the person booted withthese shoes. Moreover, the heels wear unequally.

The supportlng device which is the object of the present inventionremedies these defects. This supporting device consists of a metal plateor stiffeningsquare made of two branches from a single piece formingbetween them an angle corresponding to the one made by the meeting ofthe internal straight or curvilineal face of the heel with the interiorstraight or curvilineal face of the shank of the sole. Each of thesebranches is provided with holes for the placing in of the screwsfitting, one hole in the heel, and the other hole in the shank of thesole and the points, hooks, clasps are emplanted in these parts of theshoe, or better each of these branches is provided with one or the otherof these means of attachment.

This stifiening square should be light'and also very strong, more so inits application to shoes to harmonize with the parts by which it restsin the proper manner to preserve the outline of the shoe and to beelegant.

It is in this character that the various conformations of the stiffeningsquare represented in the accompanying drawing have been designed.

In the accompanying drawing Fig. 1 is a plan view of a shoe soleshowving the support in position.

forms of shoes with the support in position.

Fig. 1 shows a shoe illustrating the collapse of the heel after a shortusage when not fitted with a deviceaccording to the invention.

Fig. 5 shows a supporting device for a shoe in longitudinal elevationand seen from the face attachedagainst the arch of the sole.

Figure 6 is aplan view of the same. Fig. 7 shows aIIlOCllfiGClfCOIlSlIILlCtlOD of this supporting device in longitudinalelevation.

F ig. 9 shows in perspective the supporting device applicable to adifferent typeof footwear in which the metal plate, is of channelsection. 1

Fig. 10 shows in plan, seen from theface attached to the shank of thesole, the variation of the supporting device, shown in Fig. 9.

shows the various dispositions at Fig. 13 is a transverse section of theplate forming the channel.

A shows the heel, B C the supporting device applied on the heel and thisshank.

As is shewn in Fig. 1,, the line a b is longer than the line 0, d,consequently the side a b of the'sole is less resisting than c d andthis lesser resistance,in showing. itself.

by an oblique movement, causes an irregular wear of the treading face ofthe heel A.

the shank of the sole,

In applying the device C on the shank B face to face from the centre ofthe width of theheel A, one gives a much greater rigidity to the sole ofthe boot in these parts and the heels do not turn any more; one alsoavoids the sinking of the heel such as is shewn in 4:. 1 p

The supporting device in the various positionsshewn in Fig. 5. to 12as'made of a metal plate, made if necessary in tempered steel, iscomposed of two branches of a single piece an angle. The branch 1applies itself against the shank B of the sole; the branch 2 against theheel A. The angle of these two branches is curvilineal in the case where1 and 2 forming between them the supporting device applies to the Louismodel shoe so that this part carries the curve of the heel.

In the construction shewn in F igs. and 6, the plate 1 is pierced atplate 11 in one part of its length; it is provided at its eX- tremity atboth sides with hooks 12 and at the rear of such hooks with points 13.The hooks and points are introduced into holes pierced previously in theshank B of the sole, these points 13 preventing the hooks 12 from beingdisengaged when positioned.

The nail or screw lodged in the hole 5 keeps this branch on the shank.The branch 2 is curved at its end to form a centre point 14; this centrepoint 14 is driven into the heel, security being obtained by means of anail or screw inserted through the hole 15.

In the construction shewn in Figs. 7 and 8, the supporting device ismade of two laterally curving wire plates 1 spaced from each other by apierced part 16; the wires have the curve of the external face of theheel A and of the internal of the shank B; they are joined from the sideof the shank B by a transverse member 17 at the centre of the length ofwhich is a spear 18 previously implanted into the shank; the ends of theWires 1 opposite the transverse member 17 are bent to form points 14which are imbedded in the heel A. A transverse bar 19 placed a shortdistance from the pointed ends 14 is pierced by a hole 5 for thereception of a nail or screw.

In the construction or" the supporting device represented in Figs. 9,and 12 the metal plate instead of being straight in the transverse senseis curvilineal as represented in Fig. 13 and makes the form of a channel20 having rims 21 which, when applied to the shank B and against theheel A, oppose the entry of the dust and mud in the channel, the curve20 forming a rim in the plate composing the device.

In Figs. 9 and 10, the branch 1, which is applied against the shank, isturned at its end against the upper part after having been cut to formthe two points 22 bevelled at 23 outside to their extremity (see Fig.11). In forcing these points into the sole, they incline and approachone another thus following the dotted lines shown in the profile, Fig.11; between these points 22, the edges are cut into one or two points 24which are pressed into the leather. The bevels 23 are then placed insidein this case, causing the points 22 to turn aside outwardly in theleather.

Asmay be seen from the profile, Fig. 11, a notch 25 may be cut in theinternal face of these points 22, about the middle of their length, atthe point where the bevels pens trate the leather, the points 22 inbending being thus caused to take up the position shown in dotted lines.

The hooks 23 and 26 enter the leather and firmly retain the deviceagainst the sole and the teeth 24 entering at the end of the sinkingdown portion tigl'iten the leather opened by the parting of the hooks 23or The longitudinal edges 21 (Figs. 9-and 10) are provided nearly at theend 2 with hooks 27 which penetrate into the holes previously pierced inthe sole. The edges 21 may also be serrated as at 28. The device ispierced with holes 5 for holding screws.

The curved part 2 which may be applied against the heel A may beprovided in respect of the edges of the channed with points 30 intendedto penetrate the heel at the proximity of the sole. The edges 21 of thecurved part 2 are provided at their internal extremity with saw teeth 31which are imbedded in the heel; the bottom of the channel is split at 32to accommodate a screw.

In the construction of the device SllGWl'. in Fig. 12, the extremity ofthe branch 1 is constructed in the same fashion as the correspondingextremity of the branch 1 of the device sh wn in Figs. 9 and 10. Thecurved part 2 is cut on the edges 21 with saw teeth 31 and the bottom ofthe channel 20 is pierced with a hole 33 or split at to receive a screw.

What I claim and desire to secure by Letters Patent is A supportingdevice for heels of footwear comprising a metal plate consisting ofshank section. and a heel section extending a curvilineal angle, hooksextending from the opposite sides of the free end. oi' said shanksection, points formed with the free end of said shank section andextending at an angle with respect to said hooks, serrations formed withthe opposite end of said shank section, and hooks formed with said heelsection substantially as and for the purpose specified.

In witness whereof I have hereunto set my hand.
